Having-described the invention, I. claim.

1. A coupling for the confronting ends of" railway rails, comprising a sleeve including a base having-inwardly. directed flanges at the edges thereof which terminate in. up-

standing;plates,.the space between the flanges and the base of the sleeve being; of a size to receive the base flanges of the confronting ends of-rail's therein, one of the upstanding flanges being-of a greater height than the other and designed to. contact with the outer on ties and which includes a flat base having its edges formed with inwardly directed flanges that merge into upstanding plates, one of said plates being of a greater height than the other and which last mentioned plate is designed to contact with the uninterrupted side of the heads of the rails when the rails are arranged in the sleeve and to have its upper edge'flush with the tread surface of the rails, the cut-away heads of the rails being disposed overtheshorter vertical flange, filler plates arranged in the fishing spaces of the rails and contacting with the inner faces of the upstanding flanges of the sleeve, the inner filler plate having an extension at the center thereof to be received in. the cut-away portions of the heads of the rails, and means connecting the said flanges, the filler plates and the webs of the rails.

3. A coupling for the-confronting endsof railway rails, in which the heads of the said rails, from points adjacent to the, ends thereof have their inner faces cut-away in a line with the webs, theend. walls of which. being beveled. outwardly, comprising a sleeve to be spiked on ties and which includes a flat base having its edges. formedwith inwardly directed flanges that merge into upstanding plates, one of said plates being of a greater height than the other and which last mentioned plate is designed to contact withv the uninterrupted side of the heads of the rails when the rails are arranged in the sleeve and to have its upper edge flush with the tread surface of the rails, the cut-away heads of the rails being disposed over the shorter vertical flange, filler plates arranged in the fishing' spaces of the rails and contacting with the inner faces of the upstanding flanges of the sleeve, the inner filler plate having an extension at the center thereof whose ends are beveled'inwardly to be received in the cut-away portions of the heads of the rails,

and means connecting the said flanges, the

filler plates and thewebs of the rails.
